Schedulers are tools or systems that manage the timing and execution of tasks or events. They help organize when specific activities should occur, ensuring that resources are used efficiently. Schedulers are commonly used in various fields, including computing, project management, and transportation, to streamline processes and improve productivity. In computing, a scheduler determines how processes are allocated CPU time, optimizing performance and responsiveness. In project management, a project scheduler outlines timelines and deadlines for tasks, helping teams stay on track. Overall, schedulers play a crucial role in coordinating activities and maximizing efficiency across different domains.
